How to add full Internationalization support to NodeJS

Node.js has many features that make it easier to write internationalized programs. These features are based on the ECMAScript Language Specification, the ECMAScript Internationalization API Specification (aka ECMA-402), the WHATWG URL parser’s internationalized domain names (IDNs) support, and the underlying V8 engine’s use of International Components for Unicode (ICU).

If you do not have node.js installed on your system, read our guide how to install node.js

Locale-sensitive or Unicode-aware functions in the ECMAScript Language Specification

The ECMAScript Language Specification provides several functions that are locale-sensitive or Unicode-aware. These include:

• String.prototype.normalize()
• String.prototype.toLowerCase()
• String.prototype.toUpperCase()

All functionality described in the ECMAScript Internationalization API Specification (aka ECMA-402)

The ECMAScript Internationalization API Specification (aka ECMA-402) provides additional features for internationalization. These include:

• The Intl object
• Locale-sensitive methods like String.prototype.localeCompare() and Date.prototype.toLocaleString()

Easy way to enable full support is installation of NVM (Node Version Manager)

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

then install specific version of nodejs with full Internationalization support:

# install node with full icu support i18n 
nvm install -s v15 --with-intl=full-icu --download=all
nvm install -s v16 --with-intl=full-icu --download=all
nvm install -s v17 --with-intl=full-icu --download=all
nvm install -s v18 --with-intl=full-icu --download=all

Done! Now you can use all of benefits of Internationalization in NodeJS 🙂

Now when you have full icu support in nodejs, you can generate any text in any language with openai api in nodejs
